Vesicle may refer to:

In cellular biology or chemistry
  • Vesicle (biology)
    Vesicle (biology)
    A vesicle is a bubble of liquid within another liquid, a supramolecular assembly made up of many different molecules. More technically, a vesicle is a small membrane-enclosed sack that can store or transport substances. Vesicles can form naturally because of the properties of lipid membranes , or...

    , a supramolecular assembly of lipid molecules, like a cell membrane
  • Synaptic vesicle
    Synaptic vesicle
    In a neuron, synaptic vesicles store various neurotransmitters that are released at the synapse. The release is regulated by a voltage-dependent calcium channel. Vesicles are essential for propagating nerve impulses between neurons and are constantly recreated by the cell...

In human embryology
  • Auditory vesicle
    Auditory vesicle
    When the mouth of the auditory pit is closed, and thus a shut sac, the auditory vesicle , is formed; from it the epithelial lining of the membranous labyrinth is derived....

  • Optic vesicles
    Optic vesicles
    The eyes begin to develop as a pair of diverticula from the lateral aspects of the forebrain. These diverticula make their appearance before the closure of the anterior end of the neural tube; after the closure of the tube they are known as the optic vesicles....

In human anatomy and morphology
  • Seminal vesicle
    Seminal vesicle
    The seminal vesicles or vesicular glands are a pair of simple tubular glands posteroinferior to the urinary bladder of male mammals...

  • Vesicle (dermatology), a liquid-filled cavity under the epidermis, commonly called a blister

In non-human morphology
  • Subsporangial vesicle
    Subsporangial vesicle
    A subsporangial vesicle is a vesicle which is below the sporangium on a fungus.Is often used in the turgor-building and release to launch the sporangium from the stalk of the fungus using this spore-dispersal method.e.g...

  • Juice vesicles
    Juice vesicles
    The juice vesicles of a citrus fruit are the membranous content of the fruit’s endocarp. The vesicles contain the juice of the fruit. The pulp is usually removed from the juice by filtering it out...

    , the pulp found in the endocarp of common citrus members

In geology
  • Vesicular texture
    Vesicular texture
    Vesicular texture is a volcanic rock texture characterised by a rock being pitted with many cavities at its surface and inside. The texture is often found in extrusive aphanitic, or glassy, igneous rock...

    , a small enclosed cavity found in some volcanic rock, such as basalt
